AWS EC2 storage Instance


About Instance

This blog is all about what is t2 instance its pricing. At the end of the blog you will be able to decide which instance to choose from.

An instance is a virtual server in the AWS cloud. With Amazon EC2, you can set up and configure the OS and applications that run on your instance.


Amazon T2 instance was introduced to provide moderate baseline performance and ability to blast to altogether higher execution as required by your workload. Its used for workloads that don’t utilize the full CPU regularly or reliably, yet at times need to blast.


T2 instance are suited for workload purpose such as developer environment, webservers and small RDS. Amazon offer t2.micro instance for free for account less than 12 months old with some usage limit

CPU Credit


A CPU Credit is a retail strategy for CPU utilization to help diminish your bill and give future CPU time in view of past ideal time. Fundamentally, this strategy compensates your T2 instance with CPU earned credit during at server peak burst time.
For the all the CPU that you’re running occurrences don’t utilize when sit without moving, it’s additional to the CPU Credit that will be utilized time when your instances gets occupied.

As opposed to being charged a particular measure of cash each month for a specific number of cores, your bill could wind up lower if your application has a lot of ideal time.


How are CPU credits earned?

Every T2 instance begins with a solid CPU credit balance and after than  continuously inherit CPU credits every hour, dependent instance size. The accounting procedure for whether credits are collected or spent likewise at a millisecond-level. A short burst of CPU takes a little part of a CPU credit.

Unused earned credits from a given 5 minute interval expire 24 hours after they are earned, and any expired credits are removed from the CPU credit balance at that time, before any newly earned credits are added
If your instance uses all of its CPU credit balance, performance stays at the standard execution level. If this occurs in oftenly it’s recommended to use higher t2 instance


Type of AWS instance

1.Compute Optimized Instances

It is perfect for compute-bound applications that benefit from elite processors. They are appropriate for the accompanying applications:

  • Batch processing workloads
  • Media transcoding
  • High-activity web servers, greatly multiplayer on the web (MMO) gaming servers, and promotion serving motors
  • High performance computing and other process concentrated applications

2. Memory optimized Instances

Memory optimized instances are available  to deliver fast performance for workloads that process large data sets in memory.

  • High performance RDS (MySQL) and NoSQL (MongoDB, Cassandra) databases.
  • Big-data processing engines such as Apache Spark or Presto.
  • In-memory databases using optimized data storage formats and analytics for business intelligence

3. Storage Optimized Instances

Storage optimized instance are intended for workloads that require high successive read and compose access to expansive informational indexes on nearby local storage. They are optimized to convey huge low-latency, random I/O operations per second (IOPS) to applications.

  • Massive parallel processing (MPP) data warehouse
  • MapReduce and Hadoop distributed computing
  • Log or data processing applications
  • NoSQL databases and Clustered databases
  • Clustered databases
  • Online transaction processing (OLTP) systems

5. Linux Accelerated Computing Instances

If you require high parallel processing capability, you’ll benefit from using accelerated computing instances, which provide access to NVIDIA GPUs use them for graphics applications, including game streaming, 3-D application streaming, and other graphics workloads.

6. T1 Micro Instances

T1 Micro instances provide a small amount of consistent CPU resources and allow you to increase CPU capacity in short bursts when additional cycles are available. They are well suited for lower throughput applications and websites that require additional compute cycles periodically.
